KiDS

However, the new KiDS results show a discrepancy: the universe is nearly 10 percent more homogeneous than the standard model predicts.

Dr. Marika Asgari, from the University of Edinburgh, who co-led the analysis, calls the result "intriguing". "The standard model of Cosmology relies on rather mysterious physics that we call dark matter and dark energy. Scientists have to test this remarkable model in as many ways as possible, and that is exactly what we are doing."

The KiDS results may indicate small cracks in the standard model, just like another discrepancy in the expansion rate of the Universe, the so-called Hubble constant. Dr. Tilman Tröster (University of Edinburgh): "The question is whether these can be solved with a small adjustment, for example with a somewhat more complex behavior of dark matter than the simple hypothesis of totally inert 'cold dark matter'."

Leiden professor and KiDS lead Koen Kuijken cannot say whether this will eventually lead to a fundamentally different theory, for example replacing Einstein's General Theory of Relativity with a new one. "For now, I consciously try to stay away from possible theoretical interpretations, and focus on the measurements and how to make them as accurate as possible."
